Question

A mouse is running at a high speed between the kitchen and storeroom, situated along the same line in a building. A boy observes the mouse picking up pieces of bread from the kitchen and leaving them in a box in the storeroom. The boy observes the positions of the mouse after fixed intervals. He finds that the mouse travels the same displacement of 2.0 m in every half second. Starting from the door of the kitchen, the mouse reaches the door of the storeroom in 3.0 s.
On a separte sheet of paper:

a.     Make a position-time table for the motion of the mouse from the kitchen to the storeroom.

b.      Draw the particle model of this motion.

c.      Convert this model into the corresponding position-time graph.

In the box below please indicate how far the mouse traveled from the kitchen to the storeroom and describe the shape of your position-time graph.

Answer 1

i think A is the answer 

Answer 2

Answer:

The answer can be seen abelow

Explanation:

Displace-

ment(m)           time(s)

2                       0.5

4                       1

6                      1.5

8                       2

10                     2.5

12                       3

The particle has been attached below and converted into position-time graph.

The position-time graph can be used to get speed

Speed is 0.5*3*12

speed=18m/s

4. In the box below please indicate how far the mouse traveled from the kitchen to the storeroom and describe the shape of your position-time graph

The mouse gets to the storeroom and covers 3m

The shape of the position-time graph is a triangle
